T0v all fio/wm it may concern.'

Be it known that I, O'rro R. BERGER, a subject of the Emperor of Germany, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements ,in Snap-l Flasks, of which the following is a specication.

This invention relates, to a molders flask of the type generally known in the trade as a snap flask, and comprises hinged side and end sections adapted to be connected to each other by meansA of a snap latch.

Further objects ofV the invention are: to provide an adjustment of the snap lock latch for tightening it and taking up the wear; improved means for fastening separate side and end members releasably; -means for attaching an extension to the cope of' the flask; to provide adjustable and removable pins in connection with one of the Ymembers of the flask; to provide adjustable alining slots in connection with the other member of the flask, and to providean improved separable locking hinge for the hinged members of the flask.

A still further object of the invention is to provide a snap flask in which a side and end member are adjustably secured together and are connected' by means of a releasable and locking hinge to another side and end' member to form either a drag or a cope of,

the flask, the two hinged members being connected by means of a snap locking device to hold the parts in position. The object of having the side and end members separable is to permit the use of the separate sides and ends with other ysides and ends of different size so that when the flask is not in use the sides and end pieces may be taken apart for storing them in the least possi-ble space, and they are also separable for the reason that a pair of side or end members may be used with corresponding end or side members ofthe same or diffe-rent lengths for making flasks of a variety oli sizes with the smallest number of pieces of different lengths.

For the attainment of these ends andthe accomplishment of other new and useful objects as will appear, the invention consistsrin the features of' novelty in the construction, combination and arrangement of the several parts generally shown in the accompanying drawing and described in the specica'tion, but more particularly pointed out in the appended claims.

ln the drawing,Figure l is aside elevation of la flask provided with an'eXtension and Aconstructed in accordance with the principlles of my invention; Fig. 2 isa sectional detail'view of the lockingl hinge; Fig. 3 is a detail view of the alining pin and adjustable alining opening; Fig. t is a perspective of one of the hinge parts; Fig. 5 is a detail sectional view on the line V5 5 of Fig. 1; Fig. 6 is a detail sectional view on the line 6 6 of Fig; l; Fig. 7 is a detail view of the hinge; Fig. 8 is a sectional view of the latch and the wear take up; and Fig. 9 is a fragmentary view of cooperating hinged members substantially in line and partially disengaged.

Referring now more particularly to the drawing, the numerals `S, 9 land 10 designate generally a drag, cope and eXtension'of a flask of the type commonly known as a snap flask. vBoth the drag and the cope are constructed of pairs of separate side and end members. The members of each Vpair are of the same length, which may be the same length as the pair of members to which they are connected to form` the flask or may be of a different length. In practice it is intended that a plurality of pairs of both side and end members be provided dif'- fering in length so that the maximum different flasks may be formed with thel least number of pairs of' side and end members.

One of the members of which the flask is made up, as for example the cope 9, comprises end members 11 and 12 and side members-13 and One of the end members, as12, is formed adjacent one end on the outside thereofl with a slot 15 in which a bolt 16 is pivoted by means of a. Vpivot pin 17 extending through the bolt head or squared portion 18 of the bolt, and through the sides which form the slot 15. The bolt is freely movable about-the pivot pin and the extremity of theend member 12, and is formed at its outer end with a battered or an upset portion 19 to prevent the accidental removal of Va winged nut 20 from the threaded portion ofthebolt. In order to properlyl aline the side-13 and end 12 with respect to each other, one of them, as for example, the side member 13, is provided with one or more dowel pins 21 and the end member with corresponding openings 22, by means of which the n'iembers l2 and 13 are lirst positioned with respect to each other. The adjacent end of the side member 13 is formed with a slot 23 in substantial alinement with the slot 15 of the end member 12 so that the bolt 1G may be rotated into the slot 23 and the wing nut moved against the outside of the side member 13 to bind it releasably in position with respect to the end member 12. The side and end members 14 and 11 are connected to each other in a manner similar to that illustrated by Fig. 5, thus making a drag or'cope of two portions each consisting or' a side and end member. IIhese two portions, each consisting of aside and end member, are connected together by means of a hinged joint and a snap lock. rllhe hinged joint consists of lugs 24 in connection with one of the members as 13, each having a perforation and formed with an extending locking portion 26 intermediate the lugs. The end member 11 is formed at the end with lugs 27 to each of which is connected a pin 28 adapted to be moved into the perforation 25 in the lug 24 and member 11 is also formed with a proj ection 29 yadapted to interlock with the projection 26 of the member 13 and to prevent the disengagement of the members when they are substantially at right angles to each other, as shown in F 2, but to permit them to be disengaged when one of the members, as 11, is moved to the dotted position whereupon the members may be moved laterally with respect to each other to disengage the hinge. It will be seen that the projections 26 and 29 engage each other when the members are in the position shown by Figs. 2

l and 7, holding them against lateral displacement with respect to each other.

. The preferred form of locking device comprises a latch 30 pivotally connected to one of the members, as 12, and formed with a rectangular opening 31 with a slot 32 parallel thereto and adjacent one side of the opening. yThe outer extremity of the latch is formed with a projection 33 by means of which it is moved into and out of engaging position. A bolt 34 is secured to the opposite side member 14 formed with a rectangular portion 35 which is adapted to be embraced or engaged in the opening'31 of the latch. The bolt is also formed with an outer head 3G outside of the latch which helps retain the latch in position. ln order to take up the wear and tighten the opening of the latch for engagement with the rec- Atangular portion of the bolt 34, a screw 37,

having ar tapered extremity 3S is threadedV into the latch 30 with the tapered end abutting the tongue of metal formed by the slot 31, thus taking up any wear oi the latch 30 and causingy it to tightly engage the rectangular portion 35 of the bolt 34.

It will be understood that the above construction, including dowel pins, the winding nut connections, the releasable vhinge and the snap lock, apply equally well to the drag, the extension, and the cope, and in this case the extension is secured to the cope by any suitable fastening means, such, for example, as a bolt 39 inserted through proper corresponding openings in the webs of the extension and of the cope, the nut 40 holding the bolt in position. y

In order properly to aline the drag and the cope, the former is provided with perfo-` 46 is a slide 48 having an upward extension 49 with a toothed edge adapted to` interengage with the teeth 45 of the pin 42. This slide 4S is adjustable toward and from the opening 47, and toward the pin 42 by means of a slot. 50 in the slide through which a fastening device as a screw 51 extends securing it to the projection 46. This adjustable connection is provided for the purpose of taking up wear between the pins 42 and the openings 47 so that the drag and cope may be made to register as nearly as possible.

It will be understood that the drag and copel of this fiaslr are used in the ordinary well known manner, and that the cope may be provided with an extension, if desired, the sides and ends of all the parts corresponding in length so that they may readily be placed in position and disengaged with the greatest facility. Any one of the parts of the iask may be readily taken apart by simply releasing the latch 30, disconnecting the hinge by the rotation and lateral movement of the adjacent members and by loosenwhereupon the separate parts may be dis connected from each other at the hinged joint as previously set forth.

`What I claim is:

1. A snap flask comprising separate side and end members, and a releasable locking hinge for said members comprising perforated projections at the end of one member and projections with pivot pins to receive the perforations at the end of the other member, each of said members being formed at the ends with a projection to aline the members with respect to each other when they are at right angles with the pins in serted in the perforation and being free from engagement with each other when the members are rotated oppositely, whereby the pins and perforaticns may be freely engaged and disengaged.

2. A snap flask comprising separate side and end members, one of which is formed at the end with spaced perforated lugs, and a projection between them forming a continuation of the inner face of the member, and the other member being provided with spaced lugs having pins projecting therefrom adapted to enter the perforationsv of the lugs of the other member and with a projection between the lugs whose rear face forms an extension of the inner side of the member, the said projections of the members being adapted to abut when the members are at right angles to each other with the pins of one member in the perforated lugs of the other, and the said projections being disposed to contact with the side of the other members to limit the movement of the members to a position at right angles to each other in one direction of movement but to permit the opposite rotation of the said members to a point where these lugs will not engage each other, thereby permitting the members to be separated by moving the perforated lugs out of engagement with the pins.

3. A snap flask comprising pair of side and a pair of end members, means to connect one side and one end member together at right angles to each other, a separable locking hinge for connecting the two side and end members previously connected together, which is divided by backward rotation and a lateral movement of the parts in this rotated position, and a releasable locking latch affixed to the members for connecting the said connected pairs together at the corner opposite the hinge connection.

l. A snap iask comprising separate side and end members, means to releasably conneet 'each side member with an end member and at right angles thereto, a releasable locking hinge for connecting the two members thus formed when they are at right angles, which is divided by backward rotation and a lateral movement of the parts in this ro tated position, and a releasable locking latch for securing the hinged members together'.

5. In a iaslr, the combination of separable side and end members, of a hinged connection therefor comprising lugs at the ends of the side and end members, the lugs of one of the members being each provided with a perforation and the lugs of the other member being each provided with a projection adapted to be inserted through the perforations and a locking projection on each of the members adapted to permit the lateral movement of one member with respect to the other when they are in one position and to prevent the lateral movement when they are at right angles to each other.

(3. In a snap flask, the combination with separate side and end members each formed at one end with coperating projections, the projections of one of the members being provided with a perforation, and pins projecting from the lugs of'the other member adapted to be inserted through the perforations of the lugs of the other member, and projections from each of the members with cooperating locking faces intermediate the lugs of each member adapted to interengage and prevent the lateral movement of one member with respect to the other when they are at right angles to each other.

7. In a snap flask, the combination with separate side and end members, one of each pair of adjacent members having pins and the other having coperating perforations which are brought into engagement when the two members are moved laterally into alinen ment, and each having a cooperating locling` projection which'engages the other and prevents the lateral movement of the members when they are rotated at right angles to each other, but still laterally in alinement; and a latch at the corner diagonally opposite the hinged connection for holding the side and end members.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 20th day of February, A. D. 1914.
